title: The interrelation of magnetic and dielectric properties of Co(x)Mn(₁ - x)S solid solutions.
abstract: Magnetization of the cation-substituted Co(x)Mn(₁ - x)S sulfides upon cooling in zero and 100 Oe magnetic fields at the temperatures 4-300 K has been measured. Permittivity of these materials at frequencies from 1 to 100 kHz in magnetic and dc electric fields in the 100-300 K temperature range has been determined. Change in the dielectric permittivity under an external magnetic field is found to have a maximum in the temperature ranges of T₁ ~ (110-120 K) and T₂ ~ (230-250 K). Formation of spontaneous magnetic moment and the rise of magnetic susceptibility are revealed at the same temperatures in the Co(x)Mn(₁- x)S solid solutions. Features of the magnetoelectric properties of the sulfides have been explained by orbital ordering.
